A Red Flag fire danger warning is in effect Thursday throughout the Sacramento River Valley and foothills. The dry, hot and windy conditions prompted the warning, which continues through Friday evening. Evacuation warnings were issued Wednesday in the Palermo area of Butte County due to a fire that ended up burning two outbuildings, a travel trailer and about 17 acres. Another fire broke out Wednesday afternoon in West Cottonwood. Located at the end of Sherwood Road off Gas Point Road, it burned an outbuilding and about a half acre of vegetation.
